I hunt gaint Canadains
Early season I use 4 or 5 small groups of 4 - 6 decoys 20' to 30' apart and place my blinds on the down wind side of the groups .

Later I will use a V , 2 to 3 decoys deep,4'-6' apart ,3 to 10 doz decoys total with the point up wind and the blinds just down wind to 50+ yds down wind depending on where the geese want to land .
If there is no or changing direction winds I use a X with 2 staggered rows for each leg of the X .

That way we can pick up the layout blinds and move them to theproper side of the X , depending on where the geese want to land

More decoys is not always better .
If you are getting small family groups , then I may run 8 -12 decoys ,but other times you can't have enough decoys
